Abstract: An apparatus for emulating a wireless network is provided. The apparatus includes processing circuitry configured to: generate a random number corresponding to an angle between a boresight of an antenna of a network node and a direction of a first wireless device, generate a random number corresponding to a path loss between the first wireless device and the antenna of the network node, determine network performance of the first wireless device based at least in part on the generated random number corresponding to the angle between the boresight of the antenna of the network node and the direction of the first wireless device and the generated random number corresponding to the path loss between the first wireless device and the antenna of the network node, and determine performance of the wireless network based at least in part on the determined network performance of the first wireless device.

Abstract: A self-supporting cable including an outer portion and an inner portion is provided, as well as a combination of a self-supporting cable and a suspension arrangement. The inner portion includes at least one insulated conductor and the outer portion includes a first inner surface and an external surface. The external surface is arranged to engage with a suspension arrangement. The inner portion includes a first outer surface, the first outer surface abutting against the first inner surface. The outer portion includes an outer layer and a metal tape adhered to the outer layer. The outer layer includes the external surface, and the metal tape includes the first inner surface. The first inner surface being of metal and adapted for, during local load, frictional engagement with the material of the first outer surface increases the effectiveness of a functional grip between first outer surface and first inner surface.
